“…The researchers used the perturbation method [11] and numerical methods [12][13][14] to solve such nonlinear differential equations. In the calculation of deepwater SCR installation, the catenary theory [15] can also be used, while the commercial software of nonlinear finite element program ORCAFLEX is commonly used in engineering.…”

In this paper, considering the process of deepwater SCR installation with the limitations of small deformation theory of beam and catenary theory, a mechanical model of deepwater SCR installation is given based on large deformation beam model. In the following model, getting the relation of the length of the riser, bending stiffness and the unit weight by dimensional analysis, the simple approximate analytical expressions are obtained by using Homotopy Analysis Method. In the same condition, the calculated results are compared with the proposed approximate analytical expressions, the catenary theory or the commercial software of nonlinear finite element program ORCAFLEX. Hopefully, a convenient and effective method for mechanical model of deepwater SCR installation is provided.
